    Preliminary Description: 

    The sediment is dense with a lot of clasts up to 17 cm. There is an irregular contact followed by sediment with millimetric laminations. Between 95 and 166 cm there are a few clasts (missing radiography between 143 and 164 cm). From 166 up to 213 cm the sediment is grain supported with millimetric clasts. This portion is followed by an alternation of dense sediment with laminated one (laminations are millimetric to centimetric). There are some centimetric grain supported levels. Clasts are mainly millimetric.
